SPECIFICATION forming part of Letters Patent No. 634,300, dated October 3, 1899.

Application filed Aprill, 1899. Serial No- 711,369. (No model.)

To aZZ whom it may concern.-

Be it known that I, FRANK KRABAL, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented a new Improvement in Machines for Forming and Printing Butter Cakes, of which the followingis a specification.

My invention relates to an apparatus for forming and printing butter cakes.

Heretofore in the formation of these butter cakes for table use it was customary to use a hand-m old to stamp the cake of butter. This required manual insertion of the butter Within the mold by hand and the removing of the same from the mold in like manner, so making the operation tedious, lengthy, and unsatisfactory, as well as not making a uniform cake, as the butter cake would be injured somewhat in its removal from the mold.

The object of my invention is to provide such a form of apparatus in which the butter can be fed thereto in a lump or heap and the butter cakes formed and printed in any design required at one and the same operation and in a cheap and rapid manner without.

waste or injury to the cake whatever.

My invention consists, generally stated, in the novelarrangement,construction,and combination of parts, as hereinafter more specifically set forth and described, and particularly pointed out in the claims.

To enable others skilled in the art to whic my invention appertains to construct and use the apparatus, I will describe the same 'more fully, referring to the accompanying drawings, in which- Figure 1 is a side view of the apparatus. Fig. 2 is a top view thereof.

view, partly in section, of the forming-roll, showing a portion of the printing-roll; and Fig. 4 is an enlarged sectional view of one of the forming-cups removed from the formingroll.

Like numerals herein indicate like parts in each of the figures of the drawings,

As illustrated in the drawings, 1 represents the apparatus, which is provided with the supporting-frame 2, composed of the two standards 3 3 and held together in any suitable manner. Between the standards 3 3' is the forming-r0114, which is preferably formed of Fig. 3 is a sidev wood, and is mounted upon the shafts or trunnions 5 5, journaled'within the standards 3 3. The forming-roll 4 is provided with a number of openings or seats 6 around its periphery, which communicate with the central cavity or hollow portion 4 of the roll 4. Secured within each of the seats 6 are the cake-forming boxes 7, which are preferably formed of metal, open at both ends, and have a flange 7 at the other end thereof, which is adapted to fit within a seat in the periphery of the forming-r0114 and be secured thereto by means of bolts 8', passing through openings S in said flange 7 and entering said roll 4. Mounted within each one of the boxes 7 are the sliding boxes 9, whichare preferably formed of metal and provided with closed outer ends 9 to form the bottom of the mold 10 in the boxes 7. These sliding boxes 9 are provided at their inner ends with the flanges or lugs 11, which extend out from the sides of the boxes 9 and travel within slots 12, formed on theinuer end of the formin g-boxes 7. Pressing loosely against the rear face of each one of the closed ends 10 of the sliding boxes 9 are the sliding bars 13, which fit within the sliding boxes 0 and extend across the hollow portion 4' of the roll 4. These bars 13 are provided with the bent or offset portions 14 at their inner ends within the boxes 9, and their outer or opposite ends are adapted to pass out through openings 16 between the seats 6, so as to extend beyond the periphery of said roll 4. The sliding bars 13 are staggered within the roll 4, and the bent or offset portions 14 thereon permit a number of them to be used and pass each other within the narrow hollow portion 4' of said roll 4.

Supported between the standards 3 3' on the same horizontalaxis as the forming-roll 4 is the operating and printing roll 17, which is preferably formed of wood and is mounted upon shafts or trunnions 18 18, journaled within standards 3 3. This roll 17 is provided with a series of pins 19, secured within the roll 17, which are staggered or adapted to break joint with each other and extend out a sufficient distance from the periphery of .said roll 17 so as to engage with the ends 15 of the sliding bars 13 in the forming-roll 4. The roll 17 can also be provided on its periphery with any suitable print or design,

such as is shown at 20, for printing or forming a design on the roll 17 opposite molds 10 in the boxes 7 and can be either indented within or raised above the periphery of said roll 17, as desired. Mounted upon the trunnion 18 of the roll 17 isagear-wheelZl, which is adapted to mesh with a like gear-wheel 22 on the trunnion 5 of the roll 4, and a handle 23 is also mounted upon the trunnion 18 for operating the apparatus.

A chute 2% is secured to the standards 3 3 at one end of the apparatus beyond the forming-roll 4, and a wire scraper25 is secured to said standards 3 3 above the chute 24: for removing the butter cakes from the bottom 9 of the mold 10. A hopper 26, having an opening 26, is secured to the standards 3 3 over the pass 27, between the rolls 4 and 17, for the insertion of the butter.

The operation of my improved apparatus for forming and printing butter cakes is as follows: The batch of butter to be formed into cakes is placed within the opening 26 in the hopper 2G, and the operator in turning the handle 23 will cause the gear-wheels 21 29, meshing with each other, to revolve, and being secured to the trunnions 18 and 5 of the rolls 17 and at will revolve said rolls 17 and 4. As these rolls 17 and 4 are revolved the butter will be drawn in or fed to the pass 97 between the rolls 17 and 4'. and a snt'ficient amount will enter the mold 10 as it comes under the opening 26 in the hopper 26. During the further revolution of the rolls 17 and 4 this mold 10, being filled with butter, will pass around with the roll 4:, and when it reaches the central orhorizontal axis of the rolls 17 and l will meet with one of the prints or designs 20 on the roll 17 at that point, and said print or design 20 will be formed on the top of the butter within such mold 10. Each of the molds 10 in the roll 4 as they arrive under the opening 26 in the hopper 26 are filled with butter from the hopper 26, and when they arrive at the central horizontal axis the print or design 20 is print ed on the face of the butter in like manner, and as each one of the outer ends 15 on the sliding bars 13 in the roll 4 arrive at such horizontal axis of the rolls 17 and 4- they will be met by each one of the pins 19 in the roll 17, which will act to force its particular sliding bar 13 through the roll 1- and with it the particular closed end 9 of its sliding box 9, engaging with said bar 13 a sufficient distance to allow such closed end 9' to be pushed out through the mold 10, so that the closed end 9 is fiush with the face or periphery of said roll at. This will cause the butter cakes formed in the molds 1.0 to be brought flush with the face of the roll 1 and adhere to the bottom or closed ends 9, formingthe mold 10, and as such cakes arrive at the wire scraper 25 they will be caught thereby and removed from the end 9 and face of the roll 5 so that they can slide down the chute 91- and drop into any suitable receptacle. During the further revolution of the roll -l as each one of the sliding bars 13 assumes a vertical position it will drop back by gravity and with it its particular sliding box 9 to its position required to form the mold 10 within the box 7, so that it can pass under thehopper 26 and be filled with butter through the opening 26 therein in order to form the cake when it arrives at the horizontal axis of the rolls 17 and 4 and is met by the print or design 20 on the roll 17, and at the same time one of the sliding bars 13 is met by its particular pin 19 in the roll 17 to force out the end 9' through the mold 10 to free from such mold 10 one of the butter cakes previously made, as above described. During the outward movement of the sliding boxes 9 through the boxes 7 by the sliding bars 13 the distance the end 9 on the boxes 9 is required to be moved or travel so as to be flush with the periphery of the roll a is regulated by the flanges or lugs 11 on the boxes 9 striking against the closed ends of the slots 12 in the boxes 7.

It will thus be seen that my improved apparatus for forming and printing butter cakes is cheap and simple in its construction and operation, and practical experience in the use of such apparatus has demonstrated it to be rapid and accurate in its operation of forming cakes of this character. The cakes so formed are uniform in size, and itis obvious that cakes of any material and of any size, design, or shape can be formed by such an apparatus. It is also obvious that cakes can be formed by such an apparatus without the necessity of printing or forming a print or design thereon, if desired.

Various modifications in the construction and design of the various parts of the apparatus may be resorted to without departing from the spirit of the invention or sacrificing any of its advantages.
